We're quite enjoying these Pokémon Generations videos - the series of YouTube anime shorts showing us important events in the Pokémon games' timeline through the eyes of characters who aren't the never ageing, constantly inept Ash Ketchum (don't argue, he is).

One of the latest videos, entitled 'Legacy', sees International Police officer Looker meet up with Silver, who was your rival in Pokémon Gold and Silver.

Since the games were released (1999 in Japan, 2000 in the States, and 2001 in the UK) fans have debated whether the red haired Poké-thief was actually the estranged son of Team Rocket boss Giovanni, who disappeared after you beat his criminal organisation and then defeat him as a Gym leader in the first games.

The DS remakes Pokémon HeartGold and SoulSilver all but confirmed the fan theories, but only if you had a super rare Celebi given away at very limited events (or you cheated).

Take Celebi to Ilex Forest shrine and you get taken back in time to see Giovanni and Silver argue before the former leaves, but the English version never actually states the pair are father and son.

So that's one lot of theories closed, but a whole host of new ones have opened up - will Giovanni make a return in upcoming Pokémon games?

It's no secret that Pokémon Sun and Moon are trading heavily in Red and Blue nostalgia, with Alolan forms for many Kanto Pokémon and Professor Oak's cousin appearing in the games.

We'd totally be up for that, some of the teams (Team Galactic and Team Flare especially) have really failed to make any sort of impact, and while Team Rocket wasn't the most efficient evil organisation (that'd be Cipher from Colosseum), the original bad guys definitely made a lasting impression.
